Abstract
A micro light-emitting device includes an epitaxial structure layer, a first-type electrode, a second-type electrode, and a light guide structure. The epitaxial structure layer has a top surface and a bottom surface opposite to each other and a plurality of first grooves located on the top surface. The first-type electrode and the second-type electrode separated from each other are disposed on the epitaxial structure layer and located at the bottom surface. The light guide structure is disposed on the epitaxial structure layer. The light guide structure covers a portion of the top surface and a portion of inner walls of the first grooves to define a plurality of second grooves corresponding to the portion of the first grooves.
